X pipe on L99 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Any one swap out the stock center resonator on an L99 with an X pipe and keep the rest of the exhaust stock?

Hows it drive and sound?

Thanks

Sounds like you want drone when the engine goes into AFM. The resonators are there to work with the mufflers, and stop it from droning in 4 cylinder mode. Remove them, and you will have drone. You can stop it from going into AFM by getting something like a diablo tuner that has the option to turn it off. Then the X-pipe would sound better.
